Hi GentsI am still completly happy with this beautiful Bobby and love to fly it. There is only one thing that I miss. Although they work quite clean toaday I like it a lot if you can "see" the engines work .i.e. if they "smoke" a little bit, therefore my question is:Is there anybody who knows how to make the enginges of the PMDG737NG smoke??I do not mean vapour trails, I mean the dirty stuff ;-)

You can probably add some smoke using a FS9 effect file..but this is cool aswell.Look for "737heat.zip" in the library. It adds the heat effect behind the 737's engines.

thanks for the hint! I will try that one
